First we talk about a simple thing -- pure MP3 output. I've tested your SVN
buid and have found that it still produces bad (shorter) file when I use abr
option. Though if I use cbr option, I get good file exactly as RC1 and RC2
do for cbr. So, I can conclude, that SVN's "migrate" from stable to unstable
versions and back :) What can I say... That's a development process...
Though it would be great if this thread would be noticed by someone, who
deals with this subject...
I yet need to test "your" SVN build for mute video production, therefore I'd
like to know your opinion about how (if) -vf harddup option (as well as -mc
0) could help to make MEncoder to be more stable in several video formats
conversion into mute FLV. Will it be better to use them always, when I
produce mute video using -nosound option?
I'm asking this because I still consider 3-pass encoding, (because of
1. A mute FLV production
2. Pure MP3 with CBR production
3. Muxing FLV + MP3 by my own utility.

I'm afraid you just did not notice missynch for such short time. As I see
for MP3, it works just in the same incorrect way when ABR is used. Though
I'll try to use it with CBR. As for audio, it works OK. So, there is a
chance that we'll make it to work with video/audio too.

Really, I've forgotten about it... Thanks for mentioning!

Is it your 25780 or some newer? I saw a lot of "Skipping frame!" messages if
I use your build with ABR option. Though all is going OK if I use CBR.
Thank you for your help!
